Of course not.
If any smaller route exists in the routing table, you can advertise the
summary. If you don't even have a smaller route in the routing table you can
make one with a route to null0 254, and redis static to eigrp, then make the
summary.
This is why eigrp by default installs the summary with ad 5 to null0, to
allow the summary not to cause a routing loop.

Subject: Little question about EIGRP summary address
Hello Group,
It4s necessary to configure a component of a summary route under the EIGRP
proccess to announce the summary address ?, or it is just enough having a
component of the sumary route in the routing table ?
i.e.
R1 s0/0-------------------------------- s0/0 R2 .2 -------10.0.0.0/24 lan
segment
.1 1.1.1.0/24 network .2
R2 config:
interface s0/0
ip address 1.1.1.2 255.255.255.0
ip summary-address eigrp 10 10.0.0.0 255.0.0.0
!
router eigrp 10
network 1.1.1.2 0.0.0.0
network 10.0.0.2 0.0.0.0 --> Do I need to add this to my config if I want
R2
to announce the summary route ??
!
Is this enough so R2 announces 10.0.0.0/8 network to R1,
or do I need to configure a component of the 10.0.0.0/8 network unter the
EIGRP 10 proccess ??
TIA
Julio
